Abstract

Abstract A ventilating system for an enclosed space having a plurality of air inlet ducts communicated therewith with each duct including a distributor defined by vertically spaced plates forming a peripheral discharge with the upper plate having a central aperture receiving a fan. Adjustable members are provided between the plates for varying the discharge characteristics of air and air inlet means is provided between the distributor and ceiling for inlet of air from the space into the distributor with the air inlet means having control flaps or baffles associated therewith for simultaneously controlling the air inlet from the space and the air inlet from the ducts for varying the ratio of recirculated air and fresh air being discharged from the distributor.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 141 words
A ventilating system for a space having a ceiling and an air inlet duct, a distributor disposed below the ceiling and communicated with said duct, adjustable air inlet means communicated with the space below the ceiling and above the distributor, said air inlet means being in communication with said distributor, said air inlet means including an adjustable baffle member simultaneously controlling the flow rate of air from the air inlet duct and from the space thereby varying the ratio of air from the inlet duct and from the space being discharged from the distributor, said distributor including upper and lower plates spaced from each other and defining a peripheral outlet, and adjustable means interposed between the plates peripherally thereof to vary the discharge characteristics of the air being discharged peripherally of the distributor to facilitate dispersal of air throughout the space.
Claim 2
Dependent Claim 141 words
A ventilating system for a space having a ceiling and an air inlet duct, a distributor disposed below the ceiling and communicated with said duct, adjustable air inlet means communicated with the space below the ceiling and above the distributor, said air inlet means being in communication with said distributor, said air inlet means including an adjustable baffle member simultaneously controlling the flow rate of air from the air inlet duct and from the space thereby varying the ratio of air from the inlet duct and from the space being discharged from the distributor, said distributor including upper and lower plates spaced from each other and defining a peripheral outlet, and adjustable means interposed between the plates peripherally thereof to vary the discharge characteristics of the air being discharged peripherally of the distributor to facilitate dispersal of air throughout the space.
Claim 3
Dependent Claim 55 words
The structure as defined in claim 1 wherein the upper plate of said distributor has a central opening therein communicating with the air inlet duct and the air inlet means, a fan disposed in operative association with the opening for conveying air downwardly into the space between the upper and lower plates of the distributor.
Claim 4
Dependent Claim 61 words
The structure as defined in claim 2 wherein said adjustable baffle member in the air inlet means in one position will close off the air inlet means and in another position will close off communication with the air inlet duct whereby adjustment of the baffle member will vary the ratio of air taken from the space and the air inlet duct.
Claim 5
Dependent Claim 78 words
The structure as defined in claim 3 wherein said adjustable means between the upper and lower plates forming the distributor include generally U-shaped gap plates having adjustable diverging legs extending toward the peripheral edges of the plates, and means adjustably interconnecting the plates for clamping the legs of the gap plates in adjustable position thereby enabling variation in the space between the aDjacent free edges of the gap plates for varying the air discharged between the gap plates.
Claim 6
Dependent Claim 170 words
A ventilating system for a space having a ceiling and an air inlet duct, a distributor disposed below the ceiling and communicated with said duct, adjustable air inlet means communicated with the space below the ceiling and above the distributor, said air inlet means being in communication with said distributor, said distributor including plate means generally parallel with the ceiling and defining a peripheral outlet for horizontally discharging air while substantially preventing axial downward air flow, and adjustable means mounted in said outlet for varying the outflow characteristics of air from the distributor, said air inlet means including adjustable baffle means simultaneously controlling the flow rate of air from the air inlet duct and from the space thereby varying the ratio of air from the inlet duct and from the space being discharged from the distributor, said plate means including upper and lower plates spaced from each other and defining the peripheral outlet, said upper plate having an opening communicating with the space below the ceiling and above the distributor.
Claim 7
Dependent Claim 170 words
A ventilating system for a space having a ceiling and an air inlet duct, a distributor disposed below the ceiling and communicated with said duct, adjustable air inlet means communicated with the space below the ceiling and above the distributor, said air inlet means being in communication with said distributor, said distributor including plate means generally parallel with the ceiling and defining a peripheral outlet for horizontally discharging air while substantially preventing axial downward air flow, and adjustable means mounted in said outlet for varying the outflow characteristics of air from the distributor, said air inlet means including adjustable baffle means simultaneously controlling the flow rate of air from the air inlet duct and from the space thereby varying the ratio of air from the inlet duct and from the space being discharged from the distributor, said plate means including upper and lower plates spaced from each other and defining the peripheral outlet, said upper plate having an opening communicating with the space below the ceiling and above the distributor.
Claim 8
Dependent Claim 95 words
The structure as defined in claim 5 together with fan means disposed in operative association with the opening in the upper plate for conveying air downwardly into the space between the upper and lower plates of the distributor, said adjustable means between the upper and lower plates forming the distributor including generally vertically disposed plates extending generally radially thereof, and means adjustably mounting the plates in adjustable position between the plates thereby enabling variation in the spacing between the adjacent free edges of the vertical plates for varying the air discharge between the vertical plates.
